Struct SingleDispatchData 

pub struct SingleDispatchData {
    pub name: String,
    pub default: Value,
    pub registry: Mutex<IndexMap<String, Value>>,
}

Shared state for Value::SingleDispatch — a functools.singledispatch generic function. The default implementation handles argument types with no registered override; registry maps a type name to its implementation, in registration order. Shared behind an Arc so the .register decorator (which clones the wrapper value) mutates the same table the caller dispatches against, matching CPython’s single generic-function object.

Fields

name: String

Reported name (the decorated function’s __name__).

default: Value

Fallback implementation (the originally decorated function).

registry: Mutex<IndexMap<String, Value>>

Type-name → implementation, in registration order. Dispatch walks the argument type’s MRO and picks the first match.
